Another feature of the invention is the provision of a die havingradially disposed strand engaging tool pieces which cooperate with eachother under hydraulic pressure to form a plurality of wire strands intoa wire rope, having a uniform cross sectional diameter, the strands, ofwhich are tightly compressed.

A further feature of the invention is the provision of a die comprisedof a plurality of rope engaging tool pieces, each of which isautomatically and synchronously adjustable through the medium of ahydraulic pressure controller from a master hydraulic unit under the'command of an operator.

A still further feature of the invention is the provision of a die whichis simple in construction, reliable and efficient in operation, andinexpensive to manufacture and install.

With these and other objects in view, the invention consists in thefeatures of construction, and the combination and arrangement of parts,all as will be hereinafter fully described, illustrated in theaccompanying drawings, which dis` close a preferred embodiment oftheinvention, and pointed out in the claims hereunto appended.

In the accompanying drawings- Figure 1 is,an elevation of a dieconstructed in accordance with the invention.

Figure 2 is a fragmentary plan view thereof, l

adjuncts of the same being partly in section.

Figure 3 is a fragmentary view similar to Figure 1 looking toward theopposite side thereof.

Figure 4 is a sectional view taken on,the line 4-4 of Figure 2 lookingin the direction of the arrows.

Figure 5 is a perspective view of one of the work-engaging tools of thedie.

Figure 6 is a perspective view of one of the tool plungers removed fromthe die.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, the die conring or line 24 is a mthat the tool pieces stituting the present invention comprises asubstantially hexagon-shaped hollow head designated generally at erablyof steelclosed at one end by an end plate I I which at the outerperiphery thereof is shaped to correspond tothe head and is detachablysecured in place by fasteners I2. Interiorly of body I0 and integraltherewith is a core I3 which extends 'the full length of the body andwhich is formed with radially disposed guideways I4 which open into eachother at its longitudinal central axis. The grouping of these guidewayscorresponds to the spoke formation in a vehicle wheel and in theirlengths are co-extensive with the longitudinal extent of the body Ill. vWorking within the guideways I4 and coextensive therewith are workengaging tools or tool pieces I5, each having an outwardly taperedconcave working face I8 coextensive with the length thereof.

Mounted exteriorly on the body I0 on the central portion of the flatexternal faces I1 thereof are a plurality of plunger cylinders I8, eachhaving a base flange I9 attached by fasteners I9' to the face I1.Recipi'ocatingly mounted interiorly of each such cylinder is a plunger2li having a reduced fulcrum stem 2l making contact with a cup or ballfulcrum 22 the cup 23 therefor being counterseated in an adjacent toolpiece I5, which plunger 20 automatically adjusts its associated toolpiece I5 in the working of the die as a unit.

Concentrically above the body III is a pressure feed ring or line 24having inwardly directed radial branches 25 aligned with the cylindersI8 and terminating in nipples 26, while leading to ain feed conduit 21which extends from a master hydraulic pressure pump unit installed in arope machine (not shown). The master unit is under the control of theoperator of the machine. Uniform hydraulic pressure is transferred tothe cylinders I9 through ring 24 for the operation of the plungers 20therein ,so I5 will approach each other automatic adjustment thereofunder pressure for the formation of a wire rope from a group of wirestrands (not shown).

The strands of' wire for the formation of the through the wire rope aredirected through the circular open way 28 created by the channeled facesI6 of the Vtool pieces I5 and the head A and under pressurehydraulically tool pieces I5 are compressed about the strands of wirepassing through and filling the opening 28 thereby compressing thesestrands into a wire rope body as such 'strands are passed through thedie and its vequipment by a rope mak- The plate l ing machine. I has thecenter hole A, including a, body I0 pref-v 3 29 registering with the way28 between the tool pieces I5 for the passage of the formed rope fromthe die. When the wire rope is finished the pres-v sure on the work toolpieces l5 is relieved 4and when these are subjected to pressure thelatter is uniform throughout the series of pieces.

The die, by reason of the construction as before described, issusceptible of adjustment to any desired size rope within its range. Inthe operation of the device the rope is initially passed into the diewith all pressure released and when the strands of wire have beeninitially inserted the operator controls the master unit to put thedesiredpressure on the tool pieces l5 for the successful operation ofthe die vin the wire rope formation. h Y

From the foregoing it will now be seen that there is herein provided adevice accomplishing all the objects of this invention, and others,including many advantages of great practical utility and commercialimportance.

As many embodiments may be made of the inventive concept, and as manymodifications may be made in the embodiment herein shown and describedit is to be understood that all matter herein is to be interpretedmerely as illustrative and not in a limiting sense.

What is claimed is:

1. A die of the character described, comprising a head having aplurality of centrally disposed automatically adjustable tool piecestherein grouped to form a strand wire rope-way therebetween, andindividual hydraulic plunger means operable upon each of said pieces forexerting uniform pressure thereon throughout the group.

2. A die of the character described, comprising a head having aplurality of radially disposed automatically adjustable tool piecestherein grouped to form a strand wire rope-way therebetween, hydraulicmeans operable upon said pieces for exerting uniform pressure thereonthroughout the group, the last mentioned means includingindividualfulcrum plungers acting directly onvsaid tool pieces at their midpoints.

3. A die of the character described, comprisving a head having aplurality of radially disposed automatically adjustable tool piecestherein grouped to form a strand wire rope-way therebetween, hydraulicmeans operable upon said piecesfor exerting uniform pressure thereonthroughout the group, the last mentioned means including fulcrumplungers acting directly on said tool pieces, and means for exertingpressure on the respective plungers.

4. A die of the character described, comprising a head having aplurality of radially disposed automatically adjustable tool pieces'therein grouped to form a strand wire rope-way therebetween, hydraulicmeans operable upon said pieces :for exerting uniform pressure thereonthroughout the group, the last mentioned means including fulcrumplungers acting directly on said tool pieces, means for exertingpressure on the respective plungers. and a core within the head andhaving guideways for each ,of said tool pieces.
